Sample prjoject and to sample pictures

In 4.1.2015.8062 I could use ColorEach for setting different color on each data point in an PolarSerie.

After upgrading to 4.1.2017.10193 all the Point have the same color.

In the attachment is sample code and two Pictures.

Hello Tomas,

this is a change in behavior, but this change now brings the Polar series in line with other series types in TeeChart - in order for ColorEach to work there must not be any custom colors assigned to series points, e.g.

		private void InitializeChart()
		{
			Steema.TeeChart.Styles.Points serie = new Steema.TeeChart.Styles.Points();

			//Steema.TeeChart.Styles.Polar serie = new Steema.TeeChart.Styles.Polar(); //Polar series now works the same as Points series

			serie.Add(0, 50, "tag1", Color.Red);
			serie.Add(90, 75, "tag2", Color.Blue);
			serie.Add(180, 25, "tag3", Color.Green);
			serie.Add(270, 35, "tag4", Color.HotPink);

			serie.ColorEach = true;
			serie.Colors.Clear(); //this line clears custom
                                              //colors (HotPink etc.)

			tChart1.Series.Add(serie);
		}
